Yokogawa RAKD41-G4SS-31VSE-T80NNN/K8/KS1

Differential Pressure Transmitter

The Yokogawa RAKD41-G4SS-31VSE-T80NNN/K8/KS1 is a high-performance differential pressure transmitter from Yokogawa's DPharp EJX series, configured with a remote diaphragm seal system. This sophisticated instrument is designed for precise level, flow, and differential pressure measurements in demanding process applications where direct mounting is impractical or process media requires isolation.

Key Features and Product Highlights

Advanced Sensor Technology: Features Yokogawa's proprietary silicon resonant sensor technology, providing exceptional accuracy (±0.04%), stability, and reliability for critical process measurements.
Remote Diaphragm Seal System: Includes a capillary and diaphragm seal to isolate the transmitter from process media, ideal for high-temperature applications, viscous fluids, corrosive media, or slurry services.
Comprehensive Safety Certification: SIL 2 (Safety Integrity Level) certification according to IEC 61508 standards, making it suitable for use in safety instrumented systems.
Digital Communication Capability: Supports 4-20mA analog output with HART 7 protocol communication, enabling advanced diagnostics, remote configuration, and seamless integration with modern control systems.
Robust Construction: Designed for harsh industrial environments with excellent vibration immunity, electromagnetic compatibility, and resistance to challenging process conditions.
Advanced Diagnostics: Integrated self-diagnostics and condition monitoring capabilities help predict maintenance needs and prevent unexpected downtime.
